DIY: Replacing the 72 pin connector inside the NES

The reason of all faulty NES systems. The 72 pin connector
So your Nintendo doesn't behave that good lately. It blinks, it boots for a while and then freezes, the graphics are full of pixels that don't belong there and many more... You've blown the carts, you've cleaned them, you have moved the cartridges left and right in the system, you even put a spoon in it so it doesn't lift all the way up for the NES to read it.

When all of these "techniques" fail, it's time to replace the 72 pin connector that is located deep inside the guts of your beloved console. It's a low-cost, fairly easy procedure, that requires almost half an hour to complete.

You will just need a Philips head scewdriver and a news 72 pin connector that you can get on eBay from just 10$.

I will describe it in 7 easy steps:

Step 1: Unscrew the 6 main screws on the bottom of your NES and the 2 controller port screws.

Step 2: Unscrew 7 screws that hold the metal plate into place. Remove it.

Step 3: Unscrew 4 screws that hold the cartridge loading tray. Remove it.

Step 4: Unscrew 3 screws that hold the motherboard into place. Lift it up a little bit and turn it over.

Step 5: Disconnect the cables that are connected on the motherboard. Take it out.

Step 6: Remove the metal plate that covers the motherboard. Turn the motherboard over again so you can see the 72 pin connector.

Step 7: Pull the 72 pin connector back and take it out. Clean the contacts on the motherboard VERY GOOD with contacts spray. Put the new connector in.

That's it. Now just reverse the procedure to assemble your NES and you 're done. You have a brand new system that plays the games on the first pop just like the old days when you bought it fresh from the store! Enjoy!
